REMOVED FOR MAJOR RESTRUCTURING ! i am doing many changes
to accompany automatic entity to navmesh handling by setting a flag for
enities/terrain to be navmeshed and also adding my own experimental area manager
which automaticly updates an area with a thread every so often to support
dynamic world changes , the world could be divided into small managers by specifying
an area to update(like a bounding box) for each manager and these managers will
then do a lookup in their area to find any entity geometry marked by a certain flag
and then rebuild the navmesh for that geometry in that area on a thread so when
an entity is removed/added/moved in an area manager's area that manager will reflect the changes
to the navmesh in that area (almost like the tempobsticles/tilecache of recast)
also i am looking into streaming tiles on demand and streaming tiles by prebaked navmeshing .....
